In this potter movie it seemed it didn't live up to the book as I had read it before hand. David Yates seemed to put in all action moments and hardly any emotion at all. If you have not seen the eighth harry potter movie then I would recommend you do not see it in IMAX 3D as the characters were blurred and hardly any of the action scenes came out of the screen at all.
And Nevile Longbottom seemed to do more than Harry Potter, the main character.
In conclusion, the movie and it's 3D does not live up to reviews and news you have probably seen somewhere.
Even though this was, in my opinion, the worst harry potter movie. I will be sad to see the series go...
